# Examples

These gifs were created using [Charm VHS](https://github.com/charmbracelet/vhs).

VHS has a problem rendering some background color transitions, which shows up in several examples
below. See <https://github.com/charmbracelet/vhs/issues/344> for more info. These problems don't
occur in a terminal.

## Demo ([demo.rs](./demo/))

This is the demo example from the main README. It is available for each of the backends.

```shell
cargo run --example=demo --features=crossterm
cargo run --example=demo --no-default-features --features=termion
cargo run --example=demo --no-default-features --features=termwiz
```

![Demo][demo.gif]

## Barchart ([barchart.rs](./barchart.rs)

```shell
cargo run --example=barchart --features=crossterm
```

![Barchart][barchart.gif]

## Block ([block.rs](./block.rs))

```shell
cargo run --example=block --features=crossterm
```

![Block][block.gif]

## Calendar ([calendar.rs](./calendar.rs))

```shell
cargo run --example=calendar --features=crossterm widget-calendar
```

![Calendar][calendar.gif]

## Canvas ([canvas.rs](./canvas.rs))

```shell
cargo run --example=canvas --features=crossterm
```

## Chart ([chart.rs](./chart.rs))

```shell
cargo run --example=chart --features=crossterm
```

## Colors ([colors.rs](./colors.rs))

```shell
cargo run --example=colors --features=crossterm
```

![Colors][colors.gif]

## Custom Widget ([custom_widget.rs](./custom_widget.rs))

```shell
cargo run --example=custom_widget --features=crossterm
```

This is not a particularly exciting example visually, but it demonstrates how to implement your own widget.

## Gauge ([gauge.rs](./gauge.rs))

Please note: the background renders poorly when we generate this example using VHS.
This problem doesn't generally happen during normal rendering in a terminal.
See <https://github.com/charmbracelet/vhs/issues/344> for more details

```shell
cargo run --example=gauge --features=crossterm
```

![Gauge][gauge.gif]

## Hello World ([hello_world.rs](./hello_world.rs))

```shell
cargo run --example=hello_world --features=crossterm
```

This is a pretty boring example, but it contains some good comments of documentation on some of the
standard approaches to writing tui apps.

## Inline ([inline.rs](./inline.rs))

```shell
cargo run --example=inline --features=crossterm
```

cargo run --example=layout --features=crossterm
```

```shell
cargo run --example=list --features=crossterm
```

## Modifiers ([modifiers.rs](./modifiers.rs))

```shell
cargo run --example=modifiers --features=crossterm
```

```shell
cargo run --example=panic --features=crossterm
```

![Panic][panic.gif]

## Paragraph ([paragraph.rs](./paragraph.rs))

```shell
cargo run --example=paragraph --features=crossterm
```

![Paragraph][paragraph.gif]

## Popup ([popup.rs](./popup.rs))

```shell
cargo run --example=popup --features=crossterm
```

Please note: the background renders poorly when we generate this example using VHS.
This problem doesn't generally happen during normal rendering in a terminal.

## Sparkline ([sparkline.rs](./sparkline.rs))

```shell
cargo run --example=sparkline --features=crossterm
```

```shell
cargo run --example=table --features=crossterm
```
